flask plus json

We’ll use Django to take JSON-RPC requests. It should respond to “ping” with “pong”.

Install jsonrpcserver to process the JSON-RPC requests:

$ pip install jsonrpcserver

Create a views.py:

from django.http import JsonResponse
from django.views.decorators.csrf import csrf_exempt
from jsonrpcserver import method, dispatch

def ping():
    return "pong"

def jsonrpc(request):
    response = dispatch(request.body.decode())
    return JsonResponse(
        response.deserialized(), status=response.http_status, safe=False

Start the development server on port 5000:

$ python manage.py runserver 5000

Use jsonrpcclient to send requests:

$ pip install "jsonrpcclient[requests]"
$ jsonrpc --send http://localhost:5000 ping
